Abstract
It has been demonstrated that cowpea chlorotic mottle virus RNA encapsulated in phosphatidyl serine/cholesterol reverse evaporation vesicles (REV) could infect cowpea mesophyll protoplasts under conditions known to enhance liposome-protoplast interactions. Positively charged phosphatidylcholine/stearylamine multilamellar liposomes did not deliver functional CCMV RNA despite their very high nucleic acid trapping capacity and their high affinity for protoplasts.
